This is carried to the inspection of the power-factor meter with metering interface under current state, or by external standard scale realization
The metering of the power-factor meter of metering interface；
(4) switch B, switch D, switch E are placed in the state of "off", remove high-grade power-factor meter or standard scale,
Block blocking；
(5) switch A, switch B, switch C, switch D, switch E are placed in the state of " closed ", it should be with the work(of metering interface
Rate factor table works normally.
The present invention devises nine fixed end electric connectors and two switches on power factor watch shell, avoids dismounting
Inspection even disconnects ray examination and leads to the problem of, to realize On line inspection and metering in situ.Work(with metering interface
Rate factor table realizes the break-make for measuring circuit by switch button, can be in the case where instrument is not dismantled, by measuring jack
External standard scale (high-grade power-factor meter) completes the metering (inspection) of power-factor meter.It can be before ensureing equipment safety
Raising productivity effect is put, table is easy to use, easy to operate.
